Frequently Asked Questions
Do I need to have this TCM programmed by a dealer?
No. This is the biggest benefit of our module. We program it to your vehicle’s specific VIN before shipping it to you. This makes it a true plug-and-play part, saving you time and the high cost of dealership programming.
Where is the TCM located on my Express 2500 van?
On the 2006-2014 Express and Savana vans, the transmission control module is typically located in the engine compartment on the right-hand (passenger) side. Always disconnect the vehicle’s battery before starting the installation.
Will this fix a P0700 trouble code?
A P0700 code is a general fault code indicating the TCM has detected a problem. While it can be caused by other issues, a failing TCM is a very common root cause. Replacing your faulty module with this pre-programmed unit often resolves the P0700 code and the specific codes it has stored.
Is this part difficult to install?
No, this is a very straightforward installation for a DIYer with basic tools or any professional mechanic. It involves disconnecting the battery, unplugging the electrical connectors from the old module, unbolting it, and then installing the new one in the reverse order. The entire process usually takes less than 30 minutes.
